摘要:
A piezoelectric inkjet printhead, and a method of manufacturing the same, includes an ink inlet for allowing inflow of ink, a plurality of pressure chambers to contain ink to be ejected, the plurality of pressure chambers being in communication with the ink inlet, a manifold formed in communication with the ink inlet, a plurality of restrictors connecting the manifold to respective first ends of the pressure chambers, a plurality of dampers at positions corresponding to respective second ends of the pressure chambers, the second ends being opposite the first ends, a plurality of nozzles in communication with the plurality of dampers for ejecting the ink, a plurality of actuators for applying a driving force to each of the pressure chambers for ejecting the ink, a damping membrane under the manifold for dampening a pressure change inside the manifold and a cavity under the damping membrane.
